Technical Field

[0002] The non-contact 3D rapid measurement device for underground mines is a high-precision measurement device that utilizes the principle of laser ranging. It is primarily used to rapidly acquire spatial 3D data of underground mines. Through laser scanning technology, this device can completely and accurately reconstruct the 3D model of the scanned object, thereby enabling detailed mapping and management of underground mines. The non-contact 3D rapid measurement device can be applied to scenarios such as rapid 3D morphological measurement of underground spaces like mine roadways and mining areas, precise delineation of ore body boundaries, monitoring of roadway deformation, and real-time control of mining progress. It provides accurate spatial data support for safe and efficient mining. The 3D laser scanning technology utilizes the principle of laser ranging to acquire 3D coordinates, reflectivity, texture, color, and other information of various points on the surface of an object over a large area with high resolution. It can quickly reconstruct the 3D model, lines, surfaces, and volumes of the measured target. The process generally consists of three stages: on-site measurement scanning, point cloud data processing, and advanced 3D detection.

[0003] When workers need to measure underground mines, they move around in the mines with handheld measuring devices. However, during use, the glass cover on the rotating head of the existing measuring devices gets covered with a lot of debris due to prolonged contact with the harsh environment.
